Abstract
WE are at present engaged in the investigation of the configurations of certain reduced aromatic systems, and have been surprised to find how relatively inaccessible is 9 : 10-dihydrophenanthrene (I). Quite apart from the appreciable difficulty of obtaining pure phenanthrene, the reduction of this hydrocarbon requires experimental procedure which is unattainable in many university laboratories. Burger and Mosettig1 effected the dihydrogenation by using a copper-chromium-barium oxide catalyst at 220°, with a hydrogen pressure of about 200 atmospheres over a period of about nine hours.
